Capacity and Configuration

This NEMIX RAM kit delivers 96GB of DDR5 memory across two 48GB modules. It is built as ECC registered RDIMM memory for server platforms that require error correction and signal buffering.

Suitable Systems and Limitations

The kit targets the Lenovo ThinkEdge SE455i V3 inferencing server and other boards that accept 288-pin DDR5 RDIMM modules at 5600 speed. Systems needing unbuffered UDIMM memory or a different pin count cannot use these modules.

Decisive Specification

Registered ECC operation with a CL46 latency at 5600 MT/s is the single attribute that determines compatibility. Only platforms designed for DDR5 RDIMM memory with matching timing and voltage will recognise the kit.

Questions about this item

Does the ThinkEdge SE455i V3 need anything besides this kit to reach 96 GB?

The server has eight DDR5 RDIMM slots, so the two 48 GB modules fill two of them and leave the other six free for future expansion.

Can I keep my existing DDR5 4800 RDIMMs installed with these 5600 CL46 modules?

Yes, the system will run all populated slots at the lowest common speed, so the 4800 modules will operate at their rated rate while the new kit runs at 5600.

How do I confirm the ECC registered DIMMs are active after boot?

Check the BIOS memory information screen — it will show 96 GB total, DDR5 5600, ECC enabled and registered mode for each installed module.
